VIBRATING ROLLER.

Application filed September My invention relates to rollers suitable foruse in printing presses and refers particularly to vibrating inlringrollers for such described use.

In roller printing presses it is essential that the ink be distributedevenly over the inking roller and to accomplish this purpose it is usualto have a plurality of inlring rollers rotatable by their movement overthe inking plate, combined with which is a roller revoluble by itsabutment upon the inking rollers and having a transversey movement alongthe faces of the inlring rollers in order to more evenly distribute theink thereon.

Such rollers are known as the vibrating rollers.

Among the desirable features which should be possessed by vibratingrollers are the following They should revolve continuously with therevolution of the inking rollers, they should have a reciprocatingmovement along the faces of the inling rollers, they should be preventedfrom side slips along the `faces of the inlring rollers, they should beeasily removed from contact with the inking rollers when desired forcleaning or repairing pur,n poses and be capable of retention in suchnoncontact position, they should be easilyv removed from and insertedinto the press mechanism, they should be positive in action.

The device of my invention possesses all of the above mentioned andother desirable properties as will be evidenced from a consideration ofmy specification and its accompanying drawings. v

In the accompanying drawings illustrating modified forms of the deviceof my invention, similar parts are designated by similar numerals.

Figure 9 is a top view of a modified form of housing.

Figure 10 is a cross-section through the line 10 10 of Figure 9.

The particular form of the device of my invention shown in theaccompanying drawings comprises a hollow roller 10, through which passesa tubular shaft 11, supported by the bearing 12 and reduced end portion13 of the roller 10. Revoluble upon and slidable upon the shaft 11 is anexternally threaded hollow spindle 14.v The interior end 15 of thespindle 14 is angularly faced or `cam edged. Transversely movable uponthe shaft 11 is a cam, or clutch, member 16, one end face of which isangularly abuttable upon the'end 15 of the spindle 14. The cam member 16has a plurality of slots 17, 17.k A coiled spring l19 is maintainedunder tension between the clutch 16 carried by the hollow shaft 11 andthe pin 20 carried by the shaft 11. The interior thread of the endliange 13 of the roller 10 meshes with the threaded spindle 14.

If the shaft 11 be retained from revolution, and the roller 10 berevolved, the spindle 14 will be maintained in non-revoluble positionupon the shaft 11 and the meshment member L 13 with the threads of thespindle 14 will cause the roller 10 to have a transverse movement alongthe shaft 11. When the pin 21 of the member 13 reaches and abuts 4uponthe stop-pin 21 and the revolution of the roller 10 around the spindle14 is prevented, the spindle 14 and the roller 10 will revolve togetheraround the shaft 11 because of the engagement of the pin 21 with the pin21 car ried by the end member 13. Similarly, when the pin 21 of themember 13 reaches and abuts upon the pin 22, the spindle 14 and theroller 10 will revolve together upon the shaft 11. It will thus be seenthatthe tension of the spring 19 and theabutment of the two cam,

or inclined faces, of the members 15 and 16 maintain the spindle 14 fromrevolution while the roller'lO is capable` of revolution around thespindle during'its transverse movement,

but when this 'transversemovement is pre-Y vented, the roller '10 andthe spindle 14 re- Ivolve together. This is a most important attributeof a device ofthischaracter as it in sures the constant revolution ofthe roller during its use.

4Within oneend of the shaft 11 and flXedly attached thereto by the pins23, 23 is an eccentrically positioned end support 24 having alongitudinally positioned slot 25. The suptended gripping member 37 and38. The

port 24 has the stop-pin 26 and the operating member 27, both integralwith the support 24.

Vithin the other end of the shaft 11 and fiXedly attached thereto by thepins 28, 28 is an eccentrically positioned end support 30 having thestop-member 31 integral therewith.

The support for the end support 24 comprises a U-shaped housing 32having the integral outwardly extended base members 33, 33, therearwardupper .face 34 of each base member being inclined downwardly andthe forward portion of each base member having a downwardly extendedclamping flange 35.

A. clamping member comprises two U- shaped members 36, 36 each havingthe eX- two U-shaped members are connected by the integral rib 39, andthe gripping members 38, 38 are connected by the integral flange 40.There is thus formed a clamping member having two upper spaced grippingmembers and two lower gripping members. Each upper gripping member 37has a rearwardly inclined threaded hole 41, within which is a threadedset-screw 42 having an angular opening 43 longitudinally therein.

Pivotally carried within the housing 32 of the end support 24 at 44 is alocking member 45 having the key 46 and the thumb piece 47. The key 46is held in normal position by the spring 48.

To attach the housing'to the roller supporting bracket 49 of a printingmachine. the housing 32 is placed upon the upper face of the bracket 49,the clamping anges 35. 35

extending over the side face thereof. The clamping member is then placedupon the opposite side of the bracket 49 with the gripping members 37,37 extended over the base 34, 34 and the gripping members 38, 38,resting against the under face of the bracket 49.

An angular tool is then placed in the holes 43, 43 of the set screws 42.42 and the setscrews screwed inwardly, the interior ends of theset-screws being inserted in the in,- clined recesses 50, 50 of the basemembers 34, 34. The inclined movement of the setscrews 42, 42 draws theclamping flanges 35, 35 into contact with the inward face of the bracket49 and the gripping members 38. 38 into contact with the lower face ofthe bracket 49, the one movement of the set-screws thus causing a firmgripping and connecting means between vthe housing and the bracket.

The housing of theend support 30 is similar to that above describedexcept that the locking means does not have the key 46, and the lowerface of the locking means has an inclined recess 51. y In Figures 5 and6 the full lines represent the device in disengaged position and thedot-and-dash lines represent it inengaged position.

The method of placing the described vibrator roller into the printingpress is as follows The housings are clamped to thev brackets as abovedescribed. Lift the left hand locking means by means of its thumbpiecev47 and slide the end 30 thereunder as far as it will go, the stopmember 31 passing thereunder through .the recess 51. Then raise theright hand'locking means by means of its thumb piece 47 and pass the end24 thereunder, allowing the key 46 to fit within the slot 24. The deviceis then the position shown in Figures 2 and 3. It will then be notedthat because of the eccentrically positioned ends 24 and 30, thevibrating roller 10 is in raised position and hence out of contact withthe inking rollers 53, 53.

To place the vibrating relier 10 in operating position, that is incontact with the inking rollers 53, 53, it is revolved 180o by liftingkey 46 from rvslot 25. It is removed by disengaging roller first, thenlifting thumbv piece 47 at end 30, drawing 30 under the cam roller outto the right.

It will be noted that the device is held free from transverse movementin both operative and inoperative positions.

vuntil end 24 clears housing and then pulling -f The modiednform ofhousing shown in,V

the shaft 11 from transverse and rotational movement.

It will be noted from the above that the cam movement of the spindle 14operates to insure a constant revolution of the vibrating roller evenwhen it abuts upon the side of the Y. y device and is prevented fromfurther transverse movement.

It will be further noted that the vibrating roller of my invention isreadily placed in an is free from side-slip and that it can be easilyremoved from and inserted within the printing press.
